Toull/ whom, (It may concern.-

Be it known that I, WILLIAM WHITE, a citizen of the United States,-residing at Chi cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Systems of Washing and Filling Locomotive-Boilers, of which the-following is a specification.

My invention relates to locomotive-boilerwashing systems, and has for its object the provision of an economic system for using the steam and water taken from locomotives brought into the roundhouse for washing out locomotives and for heating additional water to be used for the same purpose {and for refilling the locomotives. Other objects of my invention are the provision of automatically-controlled valves, whereby the temperature of the water for washing purposes may be controlled and whereby the system may be operated with the least possible manual attention.

My invention is illustrated in the accornpanying drawings, in which- Figure 1 represents certain parts of a roundhouse in elevation, showing a locomotive and the details of the connections of the different parts of my system when constructed under one form. Fig. 2 is a similar elevation in which one of the valves is controlled by a different means than that shown in Fig. 1. Fig. 3 is a diagrammatic representation of a roun house and the piping and apparatus of my washer system.

Referring to Fig. 1, I have shown a locomotive connected, through flexible hose 1 and pipes 2 and 3, with the upper pgrtion of a filtering' and separating chamber 4. From the top of this chamber the steam-pipe 5 extends into the Water-heater-6, which is provided with a plurality'of horizontal shelves 7, ar-

ranged one above the other, and at the top with a vapor-opening 8, which leads to the free air. The filtering and separating cham: her is provided with a drainpipe 9, leading from the base of the chamber to the sludgelchamber 10, and with the filtered-waterexit 11, which connects with the top of the main storage-tank 12. Leading from the base of tank 12 is the exit-pipe 13, provided with a valve 15 and connecting with the suction side of the steam-pump 16. Also connecting the pump, is provided with a T 21, one branch of which leads, through the valve 22, directly to the distributing-pipe 23, while the other branch leads, through the valve 24, to the thermostat 19-and by way of the by-pipe and valve 26 also connects with the distributing-pipe 23, which after connecting with all of the pits finally connects with pipe 23, which leads back to the heating-tank. In order that the same connecting-hose may be used to admit water to and extract steam from the top of the boiler, the valves 3 and 23 are connected by a pipe to which the hose 1 is connected. The cold-water-supply pipe 27 leads directly to the T-joint'28, and thence by way of one branch through the au tomatically-controlled valve 29 to the top of heater 7 and by way of the other branch through the automatically-controlled valve 30 to the top of the tank through the. same opening. This automatically controlled valve 29 is connected by rod 31, lever 32, and rod 33 with the float 34 and is adapted to be opened whenever the float falls below a predetermined line in the storage-tank. The valve 30 is connected by a rod 35 with the hinged gate 36, which is adapted to be moved by steam passing from the pipe 5 into theheating-tank. An opening in the base of the heating-tank 6 is connected by the pipe 42 with 'thetop of the storage-tank, which is supplied with the overflow-pipe 43, which reaches almost to the top of thetank. The live-steam pipe 37 supplies steam through the throttle-valve 38 for operating the pump and also through the manually-operated cutofi 39 and diaphragm-valve 40 to the lower part of the heating-tank The valve 40 is controlled by the thermostat 41, which extends into the storage-tank and is controlled by the temperature of the water therein, the thermostat admitting pressure to valve 40 through pipe 41*.

Referring to Fig. 2, the valve 30 is controlled by' means of thermostat 45, which is located in the pipe 5, connected between the filtering and separating chamber and the heating-chamber.

Referring to Fig. 3, in which the designa- V tion-symbols applied to Fig. 1 have been used as far as applicable, such figure showing diagrammatically in addition to that with the suction side of this pump is a coldwater-supply pipe 17, having the valve 18 therein which 1s controlled by the thermostat 19. The pressure-water exit 20, leading from shown in' Fig. 1 the layout of piping for the entire roundhous'e, 17 representing the pits over which the locomotives stand while being washed, and 48 representing the turn-table where it is brought into contact with suflicient amount of cold water to form a mixture of the desired temperature to be admitted into the storagetank 12, as will be hereinafter described. The water which is carried oii from the engine contains a large amount of scaly sediment, which passes, together with a small amount of water, through the pipe 9 into the sludge-tank 10. The hot water'which passes through the filter in. the

chamber 4 is carried directly to the storagetank. Whenever the condition issuch that cold water pours into the top of the heating,

tank by the pipe 11. The water in the stor agetank is normally maintained at the level shown by the dotted line. 50, Fig. 1, and

whenever the water is drawn ofi so that it 'falls below this line the float 34 will sink, and

thereby operate the valve 29, which. admits cold water to the top of the heating-tank and which will eventually bring the water-level again to its normal position in the storagetank when 'steam is not being admitted through the pipe 5,- it is necessary in order to maintain the temperature'of-the water'in storage-tank at a' predetermined degree to admit live steam into the lower part of the heating-tank. This is done by means of the valve 40, which is regulated by the thermostat il the la ter being governed'by the temperature of thejwater'in the storage-tank. It will be seen thatwh'enthe water inthe tank decreases in temperature sufficiently to open the valve 40 steam will be admitted into the heat' "-tank and hotwatervwill be caused to pasii own the pipe 42, and into the s'toragetank.

The pump 16 normally drawsits supply of hot water from the base of the storage-tank. As thisjwaterris maintained at a highertemperature than is desirable for washing out sired-for washing purposes When it is deengines, the pipe after leaving the pump is divided intotwo parallel by-paths,--one wa being provided with a thermostat 19, whic 1 controls the valve 17, and thereby admits cold water into the suction side of the pump when the temperature of the water as it.

passes the thermostat is greater than is de- -t fill thezboiler of the engine befor .ag'ain starting the locomotive out, the valve 24 is closed and the valve 22 is opened, so

that the thermostat will become inoperative storage-tank, thereb regulating t I 3. A locomotive-boiler washing and and all of the water will be drawn from the for the boiler at a higher tem erature than would be necessary or. desirab e for washin purposes. When it is desired to furnish col furnishing the water 1 Water to the supply-pipe 23 for scrubbing v purposes during the day or for filling boilers which are not to be fired immediately, the valve 15 in' the hotwater -supply pipe is closed and the valve 18, which may also be manually controlled, 'is'opened, so that all the water which passes through the pump will be taken directlyfrom the cold-water-' supply pipe 27 and will pass directly throu h the pipe 20 and valve 22, which will then e op'ened to thesupply-pipe 23. I

. One branch of the cold-water-supply pipe, 7

which leads to the top of theheating-tank, 1s 7 provided .With the valve 30, which is connect ed, through the'rod 35, with the hinged gate 36-, within the lower part of the heating-tank;

The steam, which enters the heating-tank through pipe 5, will open the gate 36 to.a greater or less "angle in pro ortion t9 the. amount of steam being passe in, and'at-the same time the valve 30 will beoperatedito admit cold water'in a proper proportion to make the'resulting mixtureof substantially the tem erature desiredin-the storage-tank.

The variation shown in Fig. 2 consists in controlling this co'ld-water supply to the heating-;

tank by means of the thermostat, which is governed by the tem' eraturegof the steam which is admitted'to t e heating-tank.-. D-
